SPECIFICATION forming part of Letters Patent No. 656,0 58, dated August 14, 1900.

Application filed March 2 1900. Serial No. 7,057. (No model.)

To ctZZ whom it may concern.-

Be it known that I, J EREMIAH- J OSEPH SUL- LIVAN, a citizen of' the United States, residing at Louisville, in the county of Jefierson and State of Kentucky, have invented a certain new and useful device adapted to be used on freight-cars equipped with air-brakes and on passenger-cars in case of inoperative trainpipes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a coupling-head for trains having an air-passage leading to the atmosphere outside, there being valve mechanism normally sealing the passage and exteriorlyfulcrumed lever mechanism connected to the valve, whereby with proper operative connecting means for tripping the lever the air may be escaped from the head by the operator at any point along the length of the train, thereby applying the brakes.

In the drawings, Figure 1 is a plan View,

Fi 2 is a side elevatiomFi 3 an end eleb J b Vation, and Fig. 4a transverse section, showing the valve as arranged for releasing the air from the train-pipe.

The casing or intermediate connection A has the lugs B and 0, designed to be interchangeable with the hose-couplings at present in use between cars for the purpose of making a continuous line of piping from end to end of the train,this arrangement being commonly known as the train-pipe, which is now almost universally in use and so well known that further description here is not considered necessary, the rubber gaskets D coinciding with similar gaskets in the couplings and forming a joint capable of retaining the air and one that is easily and quickly made. A port or passage E to the valvechamber F permits the air contained in the train-pipe to be released by the valve G, a cord or wire being attached to the bell-crank lever H and secured at or near the runningboard, ladder, or other suitable location enabling the person in charge to apply the brakes and control the train, the spring I, placed at the end of the valve-stem, seating the valve when the air is released. It is evident that such devices can be placed at several locations in a train-pipe before startpoint requires immediate action on the part of the trainmen, the engineer often observing the signals given too late to have the line clear for the approaching train.

I do not know of a similar device in use at this time, and as several equivalent mechanisms can be arranged I do not wish to be limited to the design shown. A wrought-iron pipe or rubber hose can be attached to the intermediate connection operated by'suitable mechanism at the top of the car and enabling in the application of the brakes.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is

1. In combination with a coupling-head, having an air-compartment, means for connectin g the two adjoining ends of a hose pipe of said passages,and an eXteriorly-fulcrumed lever engaging the valve-stem and adapted to trip the same, substantially as specified.

3. In a coupling-head having an air-compartment,the combination of means for coupling the adjoining ends of a hose-pipe thereto, a valve-chamber connected to said head parallel with the barrel thereof, a passage be tween said compartment and chamber, an airescape passage in the end of said chamber, a

valve seated in said chamber normally sealing one of said passages, and an exteriorlyfulcrmned lever engaging the valve-stein which is tripped to connect said passages,

5 substantially as specified.

4. In combination with a coupling-head having an air-compartment, means for connecting thereto the adjoining ends of a train hose-pipe, a valve-chamber connected to said Io head, an air-passage between said air compartment and chamber, a valve seated in said JEREMIAH JOSEPH SULLIVAN.
